**Bootstrap v{{ site.current_version}}** is available for download in several ways, including some of your favorite package managers. Choose from the options below to snag just what you need.
Pull in Bootstrap's **source files** into nearly any project with some of the most popular package managers. No matter the package manager, Bootstrap will **require a Sass compiler and [Autoprefixer](https://github.com/postcss/autoprefixer)** for a setup that matches our official compiled versions.
`require('bootstrap')` will load all of Bootstrap's jQuery plugins onto the jQuery object. The `bootstrap` module itself does not export anything. You can manually load Bootstrap's jQuery plugins individually by loading the `/js/*.js` files under the package's top-level directory.
Install Bootstrap in your Ruby apps using [Bundler](http://bundler.io/) (**recommended**) and [RubyGems](https://rubygems.org/) by adding the following line to your [`Gemfile`](http://bundler.io/gemfile.html):
{% highlight ruby %}
gem 'bootstrap', '~> 4.0.0.alpha3'
{% endhighlight %}
Alternatively, if you're not using Bundler, you can install the gem by running this command:
{% highlight bash %}
$ gem install bootstrap -v 4.0.0.alpha3
{% endhighlight %}
[See the gem's README](https://github.com/twbs/bootstrap-rubygem/blob/master/README.md) for further details.
If you develop in .NET, you can also install and manage Bootstrap's [CSS](https://www.nuget.org/packages/bootstrap/) or [Sass](https://www.nuget.org/packages/bootstrap.sass/) and JavaScript using [NuGet](https://www.nuget.org):
{% highlight powershell %}
PM> Install-Package bootstrap -Pre
PM> Install-Package bootstrap.sass -Pre
{% endhighlight %}
The `-Pre` is required until Bootstrap v4 has a stable release.
